Get up to speed with our latest advanced graphics research: 📝 GATE (Geometry-Aware Trained Encoding) for neural rendering. 📝 Real-time procedural GPU tree generation. 📝 Neural Visibility Cache for real-time light sampling. 📥 Download the papers: gpuopen.com/learn/public...

Our "Neural Visibility Cache" paper has been published in JCGT! Here is a link: www.jcgt.org/published/00...

I found it cool to hear the motivation for High-Frequency Learnable Encoding for NRC\NIRC\Neural Ambient Occlusion from the perspective of Kernel Machines! Classics 😊

I will be presenting our "GATE: Geometry-Aware Trained Encoding" at HPG on Wednesday at 9:50AM. See you all in Copenhagen soon! Paper link is here: diglib.eg.org/bitstream/ha...

New papers day! Preprints of our „GATE: Geometry-Aware Trained Encoding“ to be presented at HPG and „Neural Visibility Cache for Real-Time Light Sampling“ currently on Arxiv are available here: boksajak.github.io/blog/Preprin... Kudos to co-authors Daniel Meister and Carsten Benthin. Enjoy!

I received a patent trophy! Big thanks to my friends and colleagues who helped me along the way!

Started putting together a new toy gfx framework based on python with pybind11 for directx12 etc.

After many weeks of effort I finally have radiance on screen now! I’ve still got issues mostly related to my Surfel Acceleration Structure, however I’d say the results are already looking quite promising. It has kind of a hand painted look to it now :)

New blog post: Relativistic Quaternions I briefly discuss what quaternions and dual quaternions must become in spacetime in order to represent physically meaningful motions. terathon.com/blog/relativ...

The recordings from GPC24 are up, including my talk ! This contains much more information than the slides on their own. Enjoy ! www.youtube.com/watch?v=sHFb... gpuopen.com/presentation...

I wrote a new article, this time exploring a bit how some games handle refraction. I discovered quite a few interesting tricks ! www.froyok.fr/blog/2024-12... #gamedev #rendering

Remind me why folks prefer Aces tonemapper to the Reinhard (or do they)?

What urges you to write your own path tracer? Do you prefer your pixels home-made? Is it the thrill of GPU timeout debugging? Is it insanity? Tell me why we do it.

tiny_bvh has been updated to 0.4.0. Changes: 1. speedtest reports compiler, CPU, lib version. 2. Performance is improving but Embree remains KOTH. :( 3. New: BVH optimizer! 4. New: Better test scene now included. Win64-only; the old one remains the default. Next up: SBVH! github.com/jbikker/tiny...

Are you guys using HLSL 2021 in your shaders (e.g. for templates)? Is there anything preventing you from enabling HLSL2021?

The first public release of tiny_bvh is now available from Github: github.com/jbikker/tiny... tiny_bvh.h is a single-header library without dependencies that rapidly builds and traverses a BVH for you. Have a look at the example to see how easy to use it is! Feedback welcome.

Raycasting to determine room size and sending sounds to 3 reverb channels fro close, medium and far reverb. And calculating pan for each reverb. I wanted this effect when you hear big space on one side and close space on the other (when you are near the wall). #sounddesign #gameaudio #gamedev

I wrote about video game shadow techniques on my blog: 📜 30fps.net/pages/videog... I've always liked different ways to draw shadows in games. I went and tried to find visually distinct examples and explain their differences. I hope you'll find it inspiring!

I put all of my Ray Tracing Gems chapters in one place where you can download them, extracted from books into separate PDFs: boksajak.github.io/blog/RayTrac... There is: 1. "Ray Traced Shadows" 2. "Reference Path Tracer" 3. "Refraction Ray Cones" 4. "Many Lights With Grid-based Reservoirs"

New open Source Gaussian Splatting engine by @arthurperpixel.bsky.social Train & render Gaussian Splats on any hardware! AMD/Nvidia, Windows, Linux, and Android, MacOs, iOS.. directly in the browser (Chrome) & it's open source! github.com/ArthurBrusse...

Not sure if Jendrik Illner hopped onto this platform yet. Let's spread his latest issue of Graphics Programming Weekly (362) around here: www.jendrikillner.com/post/graphic...

And here my latest blog "Sampling From a Normal (Gaussian) Distribution on GPUs": gpuopen.com/learn/sampli... Shows implementation and analysis of two GPU-friendly methods for normal distribution sampling.

I haven't posted here yet, so let me share some of my recent work. Here is my "Crash Course in Deep Learning (for Computer Graphics)", available on GPUOpen: gpuopen.com/learn/deep_l...

Hi all! It's time to introduce myself here. I am Jakub, a graphics research engineer interested in ray tracing and machine learning, known for ray tracing implementations in games like Minecraft RTX, Warhammer Darktide and Cyberpunk. Also for a few chapters in Ray Tracing Gems and research papers.
